the very fact that michigan and pennsylvania, which obama carried by 16 points and 10 points four years ago -- have gotten close i think has to be an indication that the affluent suburbs, oakland, macomb, livingston in michigan, have been moving towards romney in a significant way, and i think that the democrats are giving you static analysis there. and i think there may be a dynamic at work here. the affluent suburbs are places that people generally tend to turn out in large numbers, and we've seen signs that republicans have more enthusiasm this year. i think one reason ohio is closer is that affluent suburban counties are only an eighth of the statewide votes and a warsmer michigan. >> the romney campaign is saying they're making major investment in ohio, time and money. are they making -- taking a gamble by making a bet on ohio, that if they lose, they will not have fought or invested a lot of money or time in michigan and pennsylvania, which they might win? are they making a long bet on ohio? >> well, i think they're probably making a correct bet on ohio. ohio is 18 electoral votes
